16 Claims.

My invention relates to that class of presses designed to do the worksuch as is described in United States Letters Patent No. Re. 18,931issued to George A. Rutkoskie. In that patent the wax carbon compound ismelted and the various parts of the press are heated by means ofelectricity. This produces a satisfactory press and turns outsatisfactory work but the cost of electricity as compared with otherforms of heating means is quite considerable.

20 of parts of printing presses for this purpose but so far as I amaware none of them have proven satisfactory in use. I have discoveredthat the reason forthis is owing to the feature to which I have directedattention, to wit: the critical temperature at which the wax carboncompound must be handled. It has been found in practice that if thistemperature varies even slightly, unsatis- I factory work is turned outby the press. It is also necessary that this temperature be maintainedin all of the parts of the press which contact the wax carbon compound.As the travel for the steam or hot water is considerable, more or less,condensation takes place which results in cooling work is turned out. I

My invention has for its further object to provide means for heating apress designed to handle melted wax carbon compound for printing waxcarbon spots on sheets of paper in which means 4 are provided to insurea continuous flow of the heating medium employed thereby maintaining thetemperature at any. predetermined point.

My invention has for its further object to pro- 45 vide means formaintaining the temperature of I the supply of heating medium and tohold this temperature at a predetermined point.

My means of accomplishing the foregoing objects may be more readilyunderstood by having 50 reference to the accompanying drawings which iare hereunto annexed and are a part of this specir fication in which-Fig. 1 is a top or plan view of a press equipped with my improvedheating means; 55 Fig. 2 is an enlarged detailed view of the type of theparts of the press and consequently faulty bed partly in section to showthe interior construction;

Fig. 3 is a section taken on the line 3-3 in Fig. 2;

Fig. 8 is a fragmentary detail view showing the manner of heating theink fountain;

Fig. 9 is a more or less diagrammatic'view showing the method ofinsuring a continuous flow of the heating medium.

Similar reference numerals refer to similar parts throughout the entiredescription. As shown in the drawings I have illustrated a press of theKelly type. As this construction is so well known I shall confine mydescription to those parts of it which are provided with specialattachments so as to permit of its use in printing spotsof wax carboncompound on sheets of paper. As shown in Fig. 1 the press is equippedwith a type bed I, form rollers 2 and 3, distributor roller 4, inkfountain roller 5, ductor roller 6, vibrator roller 1 and ink fountain8.

As shown in Fig. 2 of the drawings, the heating medium is introducedinto the type bed I by means of a pipe 9 which extends into acompartment ID. A number of these compartments are cast or formed in thetype bed i. The walls H and 12 of the compartment l0 terminate a shortdistance from the end I3 of the type bed I so as to permit'the heatingmedium to flow as indicated by the arrows into the compartment I4located in the right hand side. A port orpassage l5 in the wall l6 ofthe compartment I 4 is provided for the flow of the heating medium fromcompartment l4 into compartment IT. The termination of the wall 12 alsoallows the heating medium to flow into compartment I8 formed at, theleft hand side of compartment ID. The compartments I7 and iii areconnected by ports or passages 43 and 44 which permit the heating mediumto find access to a chamber 45 formed in the ink plate 46. The pipe 9 ismounted in a sleeve l9 which is secured to the front end 20 of the typebed I, as shown it is fastened by means of bolts 2| which provide atight joint between the flange 22 on the end of the sleeve I9 and thetype bed I. The sleeve I9 is mounted for reciprocation in a cylinder 23,a packing gland 24 of suitable a construction being provided to preventthe escape of fluid from the chamber 25 as the type bed I moves back andforth due to the reciprocation imparted to it by the operation of thepress.

The cylinder 23 is carried by an arm 26 which is bolted or otherwisesecured to the frame 21'! or the press. The upper part of the arm 26 asclearly seen in Fig. 5 is dividedto form a split block the upper half 28of which is secured by bolts 29 to the lower part of the block. Thisserves to hold the cylinder 23 in alignment when the type bed isreciprocated and the sleeve l9 moves back and forth within thecylinder-.23. In some cases it may be found desirable to substitute aflexible hose for the cylinder and sleeve shown, obviously this would bea mechanical equivalent of the structure described.

The ink fountain 8 is provided with a coil of pipes 30 which extendbackwards and forwards through the ink fountain to melt the wax carbonand also to secure the required uniform temperature of the wax carboncompound.

As seen in Fig. 7 I have illustrated the manner of heating the inkfountain roller. As the means employed to heat the other rollers areidentical I shall only describe a single one. The roller 5 is formedwith a central hollow space 3| which is closed by means of a plug 32which is screw threaded into the roller 5. This plug carries anoutwardly extending sleeve 33 which extends into a cylinder 34, asuitable packing gland 35 being provided which will compress the packingand make a tight joint between the cylinder 34 and the external wall ofthe sleeve 33. A pipe 35 is provided to convey the heating medium to theinterior of the roll 5, the end 31 of which terminates a short distancefrom the end 38 of the hollow space 3|. This permits the heating mediumto flow from the pipe 36 into the space intermediate the intemalsurfaceof the sleeve 33 and the external surface of the pipe 35 into a. chamber39 whence it escapes by means of a pipe 40 back to the boiler.

'As shown in Fig.4 I provide a plurality of pipes ll which pass throughthe press adjacent the rollers and a protective shield 42 in order tomaintain the parts which contact with the carbon at the requiredtemperature.

In Fig. 9 I have shown connections for conveying the heating medium fromthe boiler to the various parts of the press. As shown in the drawingswhich is more or less diagrammatic, the steam or other heating mediumflows through the pipes as indicated by the arrows coming from theboiler (not shown) it passes through pipe 41 through awalve 48 and astandard regulator 43 into pipe 50. This pipe is suitably connected bymeans of pipes 5| and 52 to the rollers 3 and 5 or any other rollerswhich are'to be heated. Pipe 53 is connected to the coil 30 in'the inkfountainB. .Pipe 54 is connected to pipe 4| for heating the variousparts of the press. All of these pipes are suitably connected to returnpipes 55 and 56.

Flow and return pipes 51 and 58 are suitably connected to pipes and andcarry the heating medium used to heat the type bed 2 of the ink plate46. The return pipes 55 and 56 are i joined together at 59 and aresuitably connected to a circulating pump 60 of any desired type. As

illustrated the pump is driven by a motor 3| suitably connected by meansof a belt 62 to the pump 80.

Operation of the pump serves to draw the heating medium continuouslyfrom the return pipes and discharges it through the discharge side ofthe pump 60 by means of pipe 63 to 11pmheater 64 which may be connectedto the boiler (not shown) or by means of a pipe 65. It will be apparentfrom this description that I have provided means whereby the operationof the pump 60 produces a constant flow of the heating medium employedwhich will be maintained 10 throughout all of the various parts of thepress as long as the pump is operated. By the utilization of theregulator 49 I am able to maintain the temperature of the heatingmedium, employed, at any predetermined degree.
